When I looked up Sudoku I found online, I found that there were multiple solutions.

The "Sudoku Checker" is useful for verifying "whether the questions you made yourself are solvable" and "whether the solutions are one".
When I check Sudoku introduced by "Sudoku Gen" (@sudokugen_bot) on Twitter,
it says "There are multiple solutions".

I found a Sudoku puzzle with a difficulty level of 198 on the web.

When I made my own Sudoku game
"Can the question be resolved?"
"Is the solution one?"
The smartphone app to check is "Sudoku Checker".
It has a function to calculate the "level of difficulty" with its own logic when checking.
The hypothesis is that the level of difficulty can be shown with that value.
100 - Hard
200 - Medium
300 - Easy

Reference: "Live Sudoku (@live_sudoku)" presented Sudoku on Twitter.
If you check it without permission ...
- Difficulty: 198

About Sudoku with a difficulty level of 265 and an advanced technique level of 1 ... (Sudoku checker)

When you make your own sudoku
"Is the question solvable?"
"Is the solution one?"
I made a smartphone app "Sudoku Checker" to find out.
It has a function to calculate the "difficulty level" with its own logic when verifying.
The hypothesis is that the difficulty level can be displayed with that value.
100-Beginner
200-intermediate
300-advanced
We have defined an index called "advanced technique level".
The number of questions that can be solved without using advanced techniques will be 0,
The higher the level of advanced technique, the more difficult it becomes.
This time, I found the question "The difficulty level is 200 even though the advanced technique is 1 or more".
There is a bug in the calculation logic and it needs to be investigated. Make a note so that you do not forget it.
Reference: If you check the Sudoku that "iSolvePuzzles"(@iSolvePuzzles) introduces on Twitter without permission ...
・ Difficulty: 265
・ Advanced technique level: 1
have become.
